Application filed September 12, 1916. Serial No. 119,661.

To all whom t may concern.'

Be it known that I, HYMAN RUBIN, a citizen of the United States, and aresident of the city of New York, borough of Brooklyn, in the county ofKings and State of New York, have invented a new and Improved Folder forSewing-Machines, of which the yfollowing is a full, clear, and eXactdescription.

My invention relates to folders for sewing machines. The object thereofis to provide an adjustable folder whereby the same can be used forvarious widths of bindings.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed.

In the accompanying drawing, forming part of the application, similarcharacters of reference indicate corresponding parts in all the views.

Figure l is a plan view of a folder embodying my invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is a cross section on line 3 3, Fig. 1;

Fig. 4 is an elevation from the opposite side of that shown in Fig. 2;and

Fig. 5 is a section through fabric trimmed by means of mv device.

Referring to the drawings, 5 is a slotted arm whereby the folder may besecured to a sewing-machine. It has a body portion 6 which carries onesection 7 of the guiding member 8. The other section 9 of the guidingmember, which is separated from section 7, has a body portion 10coperating with the body portion 6. The two sections 7 and 9 aremaintained in proper register by a pair of guiding pins 11 carried bythe body portion 6 and projecting through the body portion 10. They arealso guided at the inletto the guide 8 by anges 15 eX- tendingfrom eachsection toward the other,

the section 9 having its flange in the front, while the section 7 hasits flange in the rear. Coil springs 12 are mounted on said pins. Theends of said coil spring are nested in the body portions 6 and 10. Thetendency of said spring is to normally separate the guide sections 7 and9. This is resisted by a set screw 13 having a knurled head which passesthrough the body portion 10 and is threaded in the body portion 6. Bymeans of this set screw the distance between the sections7 and 9 may beadjusted and, therefore, different widths of binding can be used. Thelower guide section 7 has a plate 14: which guides the goods to be boundbetween the folded binder.

It will be noted that the guide 8 is formed of two independent sections7 and 9 which normally tend to separate under the action of the coilsprings 12 but are resisted by the set screw 13. The guide sectionstaper gradually from the receiving end toward the delivery end, as iscommon in this class of devices, to fold a strip upon its intermediateedges as it passes through the guide. The guide sections are so arrangedas to fold the strip passing therethrough twice, consequently presentinga clean edge A to the fabric B to be bound by C (see Fig. 5).

I claim:

In a folder, a guide for strips to be foldf ed having two independentguide sections each adapted to foldl one edge of a strip, a body portionassociated with each of said guide sections, pins carried by one of saidbody portions and engaging the other of said body portions whereby thetwo guide sections are maintained in proper register, coil springs onthe pins between the body portions normally tending to separate theguide sections, and a set screw binding the two body portions wherebythe distance between the sections may be adjusted for various widths ofstrips to be folded.

HYMAN RUBIN.
